Watch with slot antenna configuration

ABSTRACT

A wrist-worn electronic device includes a side wall formed of electrically nonconductive material, a printed circuit board, a location determining element, a bezel, and a first antenna. The location determining element is configured to receive a first electronic signal and determine a current geolocation of the electronic device. The bezel is formed of electrically conductive material, positioned above the nonconductive side wall, such that a nonconductive slot is formed between the bezel, a perimeter of the printed circuit board, and electrical connections to two of the electrical ground terminals on the printed circuit board. The first antenna is formed at least partially by an upper portion corresponding to a circumference of the bezel between the two electrical ground terminal and configured to wirelessly receive the first electronic signal and communicate the first electronic signal to the location determining element.

BACKGROUND

Wrist-worn electronic devices often include functionality that may beused to track a user's current location, distance traveled, velocity,and other performance metrics or data. This functionality may beprovided by wirelessly receiving positional information from asatellite-based positioning system such as the global positioning system(GPS). In addition, such devices may communicate wirelessly with otherelectronic devices, systems, or networks using communication protocolssuch as Bluetooth™, Wi-Fi™, or cellular signals. One or more antennasmay be included in the electronic devices to wirelessly receive signalsfrom GPS satellites and provide wireless communication with otherelectronic devices, systems, or networks.

The bezel of some conventional wrist-worn electronic devices maypartially form an antenna that wirelessly transmits or receiveselectronic signals. This principle has been used heretofore inwrist-worn electronic devices, such as watches, having a housing, bezel,and an antenna configured to transmit and receive signals communicationsystems or devices (e.g., Bluetooth™, Wi-Fi™, ANT™, etc.) and/or receivelocation signals from a satellite-based positioning system (e.g., GPS),where the antenna is integrated with at least a portion of the bezel andcoupled with a conductive component at least partially positioned in aninternal cavity of the housing. As disclosed in U.S. Pat. No. 9,172,148,the antenna may be capacitively coupled with the conductive componentpositioned in the internal cavity of the housing. As disclosed in U.S.Pat. No. 9,257,740, the antenna may be electrically connected to asecond antenna at least partially enclosed within the internal cavity ofthe housing.

The antenna or a portion thereof may include an inverted-Fconfiguration, which typically includes an upper arm (radiating leg), asignal feed connection to the upper arm from a ground plane, and ashorting pin connection to the upper arm electrically grounding theupper arm at the location of the shorting pin connection. The twoconnections to the upper arm (for the signal feed and the shorting pin)results in a configuration having an open end opposite the location ofthe shorting pin connection. The length of an inverted-F antenna istypically measured using the length of the upper arm from the open endto the opposite end of the upper arm, which is typically the location ofthe shorting pin connection. The length of the upper arm is commonlyone-fourth (one-quarter) of a wavelength of an electrical signaltransmitted or received by the inverted-F antenna. The signal feedconnection to the upper arm is typically closer to the shorting pinconnection than the open end of the inverted-F antenna. However, thelocation of the signal feed connection may be switched with the locationof the shorting pin connection, such that the open end is opposite thelocation of the signal feed connection.

Some conventional wrist-worn electronic devices may include a housingand a slot antenna to transmit and receive communication signals orreceive locations. However, the slot antenna is located entirely withinthe electronic device housing. For instance, the slot may be formedusing a plastic carrier or a plurality of vertical supports positionedon the printed circuit board. Other antenna configurations utilize aslot formed from or within an opening defined by a ground plane and abezel. Specifically, the ground plane may have a slot (opening) and oneor more antenna resonating elements may be formed above the slot toincrease the distance between the resonating elements and the groundplane. If a printed circuit board of a device forms at least a portionof a ground plane of an antenna, the slot may be formed within theprinted circuit such that it may be visible from a top view of thedevice.

SUMMARY

Embodiments of the present technology provide an electronic device thatcan be worn on a user's wrist and that includes an improved antennadesign. The electronic device may be a watch, a wrist-worn smart phone,a wrist-worn navigation device, or other wearable multi-functionelectronic devices that include a housing and a wrist band, strap, orother attachment mechanism to secure the electronic device to a user'swrist. The electronic device may include a housing including a lowersurface configured to contact a user's wrist, a side wall, an opposingupper surface, that together form an internal cavity. Although theelectronic device is typically worn on a wrist, it may also be worn onother parts of the body such as the forearm or the upper arm. The userwearing the electronic device may be involved in activities such asstreet running, trail running, jogging, hiking, walking, biking,swimming, exercising, etc. During these activities, the electronicdevice may monitor the user's current location, distance traveled,velocity, and other performance metrics by receiving wireless locationsignals from a satellite-based positioning system such as the globalpositioning system (GPS). In addition, the electronic device may bewirelessly paired with other devices such as a heart rate monitor wornaround the user's chest, a foot pod attached to the user's shoe formeasuring jogging or running cadence and distance, a bike speed andcadence sensor attached to a crank arm and wheel hub of the user'sbicycle for tracking biking performance, and so forth. Furthermore, theelectronic device may be able to communicate with smartphones, tablets,laptop or desktop computers, Wi-Fi routers, cell towers, and the like toallow the user to upload activity data, download apps, receive textmessages, emails, and weather alerts, and so on.

Embodiments of the electronic device may include a printed circuitboard, a bezel, and a first antenna. The printed circuit board mayretain electronic components which process electronic signals and mayinclude a plurality of electronic signal terminals operable to provide asignal feed and a plurality of electrical ground terminals operable toprovide electrical ground.

The printed circuit board may provide a ground plane for one or moreantennas, including the first antenna. A perimeter of the printedcircuit board may be positioned adjacent to a side wall of the housing.The circuit board may be positioned within the internal cavity enclosedby a circular lower surface. The circuit board may be substantiallycircular, rectangular, or square in shape. In embodiments, the circuitboard may have an irregular shaped such that it is partially circularand partially rectangular. The partially circular portion of the circuitboard may include a plurality of electrical ground terminals and a firstelectronic signal terminal and may be positioned such that the perimeterof the circular portion is positioned adjacent to a side wall of thehousing.

The bezel may be electrically connected to two of the electrical groundterminals and the electronic signal terminals operable to provide asignal feed (F). The bezel may be formed from electrically conductivematerial and any surface of the bezel may be electrically coupled withan electrically conductive spring contact. In embodiments, eachelectrical connection may be provided by a combination of anelectrically conductive tab extending from a surface of the bezel, anelectrically conductive spring contact, and an electrical terminal onthe printed circuit board. In other embodiments, a conductive wire mayprovide the electrical connection between the bezel and an electricalterminal on the printed circuit board. The housing may be shaped suchthat the electronic device has a circular face (e.g., a circular watchface) and the bezel may be annular in shape.

The side wall of the housing may be formed of an electricallynonconductive material, such as ceramic, plastic, or combinationsthereof. The side wall may be a single, continuous side wall or aplurality of side walls that form an internal cavity when combined witha lower surface that contacts a wearer's wrist and an opposing uppersurface. In embodiments, the side wall may include one or more openingsfor depressible buttons. The side wall provides structural supportbetween the upper and lower surfaces of the housing. In embodiments, theside wall may be formed of two or more layers, each having anon-conductivity characteristic common to or varying in comparison toother layer(s). For example, the side wall may have a nonconductiveupper layer that is formed by a different material than a nonconductivelower layer.

A nonconductive slot may be formed by a portion of a nonconductive sidewall, an air gap, or a combination thereof, bound by an upper portion, alower portion and side portions. In embodiments, the nonconductive slotmay be formed by positioning the bezel, a perimeter of the printedcircuit board, and electrical connections to the two of the electricalground terminals to enclose an area that is not electrically conductive.For instance, the nonconductive slot may be formed by a portion of anonconductive side wall located between the bezel, a perimeter of theprinted circuit board, and the electrical connections to the two of theelectrical ground terminals. In some embodiments, a width of the bezelmay exceed a width of the side wall such that an air gap exists under aportion of the bezel extending over the side wall in the internal cavitybetween the bezel, a perimeter of the printed circuit board, and theelectrical connections to the two of the electrical ground terminals.Thus, a first portion of a circumference of an electrically conductivebezel may form an upper portion of a first antenna utilizing aslot-antenna configuration.

Unlike an inverted-F antenna configuration, which typically has an upperarm (radiating leg) electrically connected to one ground (G) connectionpoint (shorting pin) electrically grounding the upper arm and one signalfeed (F) connection point from a ground plane used to transmit orreceive an electronic signal, the slot-antenna configuration has twoground (G) connection points and one feed (F) connection point. Theinverted-F antenna configuration has an open end opposite the locationof the ground (G) connection point (the signal feed (F) connection istypically between the open end and the ground (G) connection point). Thenonconductive slot formed by positioning a conductive bezel, a perimeterof the printed circuit board, and electrical connections to the two ofthe electrical ground terminals, as disclosed herein, encloses an areathat is not electrically conductive by four sides and, thus, lacks anopen end that is characteristic of conventional inverted-F antennas.

The length of the first portion of the circumference of the bezelassociated with the first antenna may be one-half of a wavelength of thefirst electronic signal as a result of the slot-antenna configurationachieved by utilizing techniques disclosed herein. The length of aninverted-F antenna is typically a quarter of a wavelength of anelectrical signal transmitted or received using the inverted-F antenna,so an inverted-F antenna configuration results in an antenna length thatmay be one-half the length of a slot-antenna configuration. The lengthof an inverted-F antenna is typically measured using the length of theupper arm from an open end to an opposite end of the upper arm, which istypically the location of the shorting pin connection.

The first antenna is at least partially formed by a first portion of theconductive bezel. In embodiments where two ground (G) connection pointsprovide outer connections (top corners of the nonconductive slot) andthe signal feed (F) connection is between two ground (G) connectionpoints, the first portion of the conductive bezel between the electricalconnections to the electrical ground (G) terminals may form the firstportion of the circumference of the bezel associated with the firstantenna. In embodiments where the signal feed (F) connection and a firstground (G) connection point provide outer connections (top corners ofthe nonconductive slot) and a second ground (G) connection point isbetween the signal feed (F) connection and the first ground (G)connection point, the first portion of the conductive bezel between thesignal feed (F) connection and the first ground (G) connection point mayform the first portion of the circumference of the bezel associated withthe first antenna.

In embodiments, the first antenna may be further formed by theelectrical connections to the electrical ground terminals and theelectrical terminals (first electronic signal terminal and the first andsecond electrical ground terminals) on the printed circuit board. Insome embodiments, the top portion of the nonconductive slot may beformed by the first portion of the conductive bezel on top, the lowerportion of the nonconductive slot may be formed by the perimeter of theprinted circuit board, which may provide a ground plane for the firstantenna, and the sides of the nonconductive slot may be formed by theelectrical connections to two electrical ground terminals on the printedcircuit board. In other embodiments, the top portion of thenonconductive slot may be formed by the first portion of the conductivebezel on top, the lower portion of the nonconductive slot may be formedby the perimeter of the printed circuit board, which may provide aground plane for the first antenna, and a first side of thenonconductive slot may be formed by the electrical connection to oneelectrical ground terminal on the printed circuit board and a secondside of the nonconductive slot may be formed by the electricalconnection to the first electronic signal terminal on the printedcircuit board.

The first antenna may be configured to wirelessly receive a firstelectronic signal, such as a GPS signal, and communicate the receivedfirst electronic signal to components positioned in the internal cavity,such as the location determining component. The location determiningcomponent may process the received first electronic signal to determinea geolocation of the electronic device.

The electronic device may include a second antenna configured to utilizethe slot-antenna configuration in some embodiments. The second antennamay be configured to transmit and receive a second wireless signal, suchas Bluetooth™, Wi-Fi, cellular, etc., and may wirelessly transmit andreceive a corresponding second electronic signal. The second antenna maybe formed from a second electronic signal terminal, third and fourthelectrical ground terminals, and a second portion of the circumferenceof the bezel. The length of the second portion of the circumference ofthe bezel associated with the second antenna may be based on awavelength or frequency (wavelength=c (speed of light)/frequency) of thesecond electronic signal, which may have a different wavelength (orfrequency) in comparison to the first electronic signal. For example,the length of the second portion of the circumference of the bezelassociated with the second antenna may be one-half (or one-fourth) of awavelength of the second electronic signal, which may have a frequencythat is twice (double) the frequency of the first electronic signal.

In embodiments, the first antenna and the second antenna may share oneor more electrical ground terminals on the printed circuit board. Forexample, one of the two electrical ground terminals associated with thefirst antenna may be electrically connected to the second antenna suchthat the electrical ground terminal is also associated with the secondantenna.

In embodiments, the first portion of the circumference of the bezel atleast partially forming the first antenna may partially overlap with thesecond portion of the circumference of the bezel at least partiallyforming the second antenna. For example, as shown in FIGS. 10b and 10c ,the first portion of the circumference of the bezel may overlap with thesecond portion of the circumference of the bezel in the portion betweenthe feed (F) and one of the ground (G) connection points on thecircumference of the bezel.

Insome embodiments, the terminals 48 may alternatively or additionally bepositioned on one or more surfaces, such as the first side of printedcircuit board 26. The terminals 48 may include a plurality of electronicsignal terminals, each of which is electrically connected to oneelectronic signal trace, and a plurality of electric ground terminals,each of which is electrically connected to electrical ground. Theprinted circuit board 26 may provide a ground plane for the firstantenna 30 and the second antenna 32.

Given that the printed circuit board 26 may be retained within internalcavity 44 of housing 12, the printed circuit board 26 may have anoutline shape and perimeter that is generally similar to the shape ofthe interior of the housing 12. In exemplary embodiments, the housing 12is generally circular, and thus, the outline shape of the printedcircuit board 26 may be circular, hexagonal or octagonal to approximatethe circular shape. Other outline shapes of the printed circuit board 26are possible including square, rectangular, or even circular. Inembodiments, printed circuit board 26 may have an irregular shaped suchthat it is partially circular and partially rectangular.

The bezel 28, as seen in FIGS. 2-3, 5-6 and 7, may be positioned on theupper surface 40 of housing 12 and may generally cover the perimeteredges of the display 14 or encircle display 14. The bezel 28 may be aring shaped to conform to the shapes of a circular or oval housing 12and display 14 such that bezel 28 may be positioned between theperimeters of housing 12 and display 14. The bezel 28 may have an outerperimeter, or outer circumference, that is substantially the same shapeas the upper surface 40 of housing 12 and an inner perimeter, or innercircumference, that is substantially the same shape as the outerperimeter of display 14. For example, the bezel 28 may have an inneredge with dimensions that are smaller than or approximately equal to theperimeter dimensions of the display 14 and an outer edge with dimensionsthat are approximately equal to the perimeter dimensions of the uppersurface of the housing 12. Thus, the bezel 28 may be circular, square,or rectangular with a central opening through which the display 14 maybe viewed. In the exemplary embodiments shown in the figures, bezel 28may have an annular shape. In various embodiments, the bezel 28 may bealigned with the lens 46 positioned atop the display 14.

The bezel 28 may be formed from any material that may integrate anelectrically conductive material, such as a metallic or semi-metallicmaterial, and may be positioned on or fixedly attached to one or morenonconductive side walls 42 of housing 12. In some embodiments, thebezel 28 may be able to rotate in place, roughly around the center ofthe upper surface of the housing 12. In other embodiments, the bezel 28may be fixedly attached to the upper surface and may not rotate. Inembodiments, the bezel 28 may be integral to housing 12. For example,conductive bezel 28 may be a raised or flush portion of housing 12 witha central opening through which display 14 may be viewed and positionedabove one or more nonconductive side walls 42.

As detailed herein, first antenna 30 may be configured as a slotantenna, which generally includes a nonconductive slot 34 formed by aportion of a nonconductive side wall 42, an air gap, or a combinationthereof. The nonconductive slot 34 may have any three-dimensional shapesuch as a substantially rectangle, a square, an oval, or a circle shapeformed in a portion of housing 12. The first antenna 30, as seen inFIGS. 2-3, 5, 6 a-6 b, and 8, is a slot antenna having a nonconductiveslot 34 in which the “slot” is formed or bound by an upper portion 30 a,a lower portion 30 b, and spring contacts 52A, 52C serving as sideportions 30 c, 30 d, respectively, of first antenna 30.

First antenna 30 generally converts wireless RF electromagneticradiation (an electronic signal) into a corresponding electronic signal.The nonconductive slot 34 through which the electric field of firstantenna 30 passes includes a portion of nonconductive side wall 42. Asignal transmitted using first antenna 30 having a nonconductive slot 34within a side wall 42 of housing 12 is output (electromagneticallyradiates) to the side of housing 12 in the far field (based onconstructive and destructive interference). Similarly, first antenna 30may receive a signal output from that direction in the far field or fromany other direction. FIGS. 2 and 3 depict components of electronicdevice 10 from opposing sides to illustrate the respective positions ofeach component, illustrating a lens, a display, and a bezel 28 removedfrom a housing 12. As shown in these Figures, a portion of bezel 28extending from tab 50A to tab 50C form an upper portion 30A of firstantenna 30. Tabs 50A-50C may contact and electrically couple with (forman electrical connection) spring contacts 52A-52C that are electricallycoupled with electrical terminals 48A-48C on the printed circuit board26.

FIGS. 5 and 6A, 6B depict components of electronic device 10 when bezel28 is positioned against the upper surface 40 of housing 12 such thattabs 50A-50C contact and electrically couple with (form an electricalconnection) spring contacts 52A-52C. In FIG. 6A, a portion of bezel 28forming an upper portion 30 a of first antenna 30 is presented and aremaining portion of bezel 28, which obstructs the view of printedcircuit board 26 and certain other components in FIG. 5, is removed toexpose printed circuit board 26 and certain components, such as tabs50A, 50C, spring contacts 52A, 52C, and electrical terminals 48A, 48C.In FIG. 6B, first antenna 30 is presented without bezel 28 obstructingthe view of printed circuit board 26 to expose printed circuit board 26,spring contacts 52A, 52C, and electrical terminals 48A, 48C.

In the depicted embodiment, spring contact 52A forms a side portion 30 cof first antenna 30 and sprint contact 52C forms a side portion 30 d offirst antenna 30. First antenna 30 is formed by a nonconductive slot 34within upper portion 30 a, lower portion 30 b, and side portions 30 c,30 d. Specifically, the nonconductive slot 34 is formed between thebezel 28, a perimeter of the printed circuit board 26, and theelectrical connections to two of the electrical ground terminals (springcontacts 52A and 52C). The nonconductive slot 34 may be formed within aside wall 42 of housing 12.

A side cross-sectional view of the illustrative first antenna 30 havinga nonconductive slot 34 having a width (W) and a height (H) is providedin FIG. 7. The nonconductive slot 34 is formed within upper portion 30a, lower portion 30 b, and side portions 30 c, 30 d. As discussed above,upper portion 30 a corresponds to a portion of bezel 28, lower portion30 b corresponds to a perimeter of printed circuit board 26, and sideportions 30 c, 30 d correspond to spring contacts 52A, 52C,respectively. In the depicted example, spring contact 52B mayelectrically couple with a first portion of a circumference of the bezel28 between first and third spring contacts 52A (G), 52C (G) and springcontact 52B may provide a signal feed (F) to first antenna 30.

FIG. 8 provides a cross-sectional view of a tab 50 (of bezel 28)contacting and electrically coupling with (forming an electricalconnection) a spring contact 52 that is electrically coupled with anelectrical terminal 48A on printed circuit board 26.

FIG. 9 is a graph illustrating antenna performance for first antenna 30when it is fed a signal in accordance with embodiments of the currenttechnology. The graph provides a plot of standing-wave-ratio (SWR)values as a function of operating frequency. As shown in FIG. 9, firstantenna 30 operates in a frequency band approximately centered about afrequency f1, which is determined by a combination of the width (W) andheight (H) of nonconductive slot 34. For example, in an embodiment, awidth (W) and height (H) of nonconductive slot 34 may be chosen suchthat the frequency f1 may be equal to one-half wavelength of anelectronic signal desired to be transmitted and/or received by firstantenna 30. First antenna may thus be tuned to transmit and/or receivedesired electronic signals by varying the dimensions of nonconductiveslot 34.

In the exemplary embodiment shown in FIG. 4, the first antenna 30 is inelectronic communication with the location determining element 18, suchthat it is configured to wirelessly receive a GPS signal from GPSsatellites. In other embodiments, the first antenna 30 may be configuredto wirelessly transmit and receive electronic signals from any of thesources discussed above and shown in FIG. 1, such as cell towers, Wi-Firouters, other electronic devices, etc.

In embodiments, the nonconductive slot 34 may be formed by a portion ofnonconductive side wall 42. For example, a nonconductive slot 34 may beformed by a portion of a nonconductive side wall 42 defined or enclosedby a portion of the conductive bezel 28 between a first spring contact52A and a third spring contact 52C (each providing an electricalconnection to an electrical ground terminal 48), a perimeter of theprinted circuit board 26 between the first and third spring contacts52A, 52C, and the first and third spring contacts 52A, 52C. A secondspring contact 52B may provide an electrical connection to an electricalsignal feed (F).

In other embodiments, the nonconductive slot 34 may be formed by acombination of an air gap and a portion of nonconductive side wall 42.For example, a width of bezel 28 may exceed a width of nonconductiveside wall 42 such that an air gap exists under a portion of bezel 28extending over side wall 42 in the internal cavity 44. Similar to theembodiment described above, the air gap may be defined or enclosed by aportion of the conductive bezel 28 between a first spring contact 52Aand a third spring contact 52C (each providing an electrical connectionto an electrical ground terminal 48), a perimeter of the printed circuitboard 26 between the first and third spring contacts 52A, 52C, and thefirst and third spring contacts 52A, 52C. A second spring contact 52Bmay provide an electrical connection to an electrical signal feed (F).Thus, the air gap may be located adjacent to the same portion of anonconductive side wall 42 defined or enclosed by a portion ofconductive bezel 28 between the first and third spring contacts 52A,52C, a perimeter of the printed circuit board 26 between the first andthird spring contacts 52A, 52C, and the first and third spring contacts52A, 52C. As a result, the nonconductive slot 34 through which theelectric field of first antenna 30 passes includes a portion ofnonconductive side wall 42 and an air gap.

In some embodiments, first antenna 30 may be formed by a combination ofelectronic signal terminal 48B (providing an electrical signal feed (F)connection) and ground terminals 48A, 48C (providing an electricalground (G) connection) on printed circuit board 26, a first portion of acircumference of the bezel 28 between first and third spring contacts52A (G), 52C (G) (corresponding to the locations of tabs 50A and 50C,respectively, when the bezel is positioned against the upper surface 40of housing 12), including the portion of bezel 28 at which second springcontact 52B (F) is connected, and a first portion of a circumference ofprinted circuit board 26 between the first and third spring contacts 52A(G), 52C (G). In this configuration, the edges of the nonconductive slot34 are the electrical ground (G) connection points to bezel 28 andprinted circuit board 26.

As shown in FIGS. 2 and 3, first antenna 30 (a slot antenna) is formedby an upper portion 30 a, a lower portion 30 b, and side portions 30 c,30 d. Upper portion 30 a, lower portion 30 b, and side portions 30 c, 30d are all in electrical and physical contact such that a nonconductiveslot 34 is formed inside these portions of first antenna 30. Upperportion 30 a of first antenna 30 is formed by a first portion of acircumference of bezel 28 extending between first and third springcontacts 52A (G), 52C (G) (corresponding to the locations of tabs 50Aand 50C, respectively) when the bezel is positioned against the uppersurface 40 of housing 12. Lower portion 30 b of first antenna 30 isformed by a first portion of the circumference of the printed circuitboard 26 extending between first and third spring contacts 52A (G), 52C(G) such that lower portion 30 b corresponds to upper portion 30 a. Sideportions 30 c, 30 d of first antenna 30 are formed by spring contacts52A, 52C, respectively. Thus, first antenna 30 operates as a slotantenna because a nonconductive slot 34 is formed by the upper portion30 a (a first portion of the circumference of bezel 28), a lower portion30 b (a first portion of the circumference of printed circuit board 26)and two side portions 30 c, 30 d (spring contacts 52A and 52C).

In other embodiments, the first portion of a circumference of the bezel28 forming an upper portion 30 a of first antenna 30 may extend betweensecond spring contact 52B (F) and third spring contact 52C (G)(corresponding to the locations of tabs 50B and 50C, respectively, whenthe bezel is positioned against the upper surface 40 of housing 12),including the portion of bezel 28 at which first spring contact 52A (G)is connected. In this configuration, the edges of the nonconductive slot34 are one electrical ground (G) connection point and one electricalsignal feed (F) connection point to bezel 28 and printed circuit board26.

The electrically conductive plane of first antenna 30, which is a slotantenna, may be provided by the ground plane of the printed circuitboard 26 and the first portion of the bezel 28 forming an upper portion30 a of first antenna 30. The nonconductive slot 34 may be provided bythe nonconductive side wall 42 of housing 12 between portions of theprinted circuit board 26 and the bezel 28 between spring contacts 52.One of the electronic terminals, such as electronic signal terminal 48B,may provide the signal feed and two of the electronic terminals, such asground terminals 48A, 48C, may provide the electrical ground for thefirst antenna 30.

A length (circumferential distance) of the first portion of thecircumference of bezel 28 utilized for the upper portion 30 a of firstantenna 30 may be based on a wavelength—typically, a one-halfwavelength—of the wireless signal to be transmitted or received by firstantenna 30. Generally, the one-half wavelength of an electronic signal,e.g., a GPS signal, determines a length along the circumference of thebezel 28 forming an upper portion 30 a of first antenna 30 that must beutilized to transmit or receive the electronic signal using the firstantenna 30. It is to be understood that the length of upper portion 30 aof first antenna 30 that must be utilized to receive an electronicsignal may account for a larger portion of a bezel 28 having a smallercircumference than a bezel 28 having a larger circumference.

Electrical connections to bezel 28 for a first and a second electricalground (G) may be provided at first and second endpoints, respectively,of the first portion of the circumference of bezel 28 occupied by thefirst antenna 30. An electrical connection to bezel 28 for a signal feed(F) may be provided at a point along the first portion of thecircumference of the bezel 28 occupied by the upper portion 30 a offirst antenna 30 between the first and second endpoints associated withthe electrical ground (G). Typically, the signal feed (F) iselectrically connected to bezel 28 at a point away from a midpoint ofthe first portion of the circumference of the bezel 28 occupied by thefirst antenna 30 (i.e., the signal feed (F) connection point is closerto one of the two electrical ground (G) connection points).

As shown in FIGS. 2-3 and 5-6, bezel 28 may include a plurality of tabs50 that electrically couple with (form an electrical connection) aplurality of spring contacts 52 that are electrically coupled withelectrical terminals 48 on the printed circuit board 26. As seen inFIGS. 2-3 and 5-7, each tab 50 of bezel 28 may be formed fromelectrically conductive material, such as metal, and may have agenerally rectangular shape to contact a spring contact 52. Each tab 50may be attached to, or integrally or monolithically formed with, theinner circumference of the bezel 28, such that each tab 50 extendsnormal to the plane of the bezel 28. Thus, when bezel 28 is placed abovenonconductive side wall 42 during assembly of electronic device 10, eachtab 50 extends downward into the internal cavity 44 of housing 12.

Each spring contact 52, as seen in FIGS. 2-3 and 5-7, may be formed fromelectrically conductive material, such as metal, and may have agenerally elongated, flat shape. In addition, each spring contact 52 mayinclude a first leaf spring 54 and a second leaf spring 56. The firstleaf spring 54 may be positioned on a first half of the spring contact52 and may be configured to make electrical contact with oneelectrically conductive tab 50 of bezel 28. The second leaf spring 56may be positioned on a second half of the spring contact 52 and may beconfigured to make electrical contact with one electrical terminal 48 onthe printed circuit board 26. Each spring contact 52 may be retained onan inner surface of nonconductive side wall 42.

The electrical connection for the first antenna 30 from bezel 28 to theprinted circuit board 26 may include one tab 50 of bezel 28 contactingthe first leaf spring 54 of one spring contact 52, and the second leafspring 56 of the spring contact 52 electrically contacting one terminal48 on the printed circuit board 26. Other embodiments of the electronicdevice 10 may include other electrical connection structures between theconductive bezel 28 and terminals 48 on the printed circuit board 26,such as pogo pins, electrically conductive wires, electricallyconductive cables, flexible printed circuits, and so forth.

The second antenna 32 (also a slot antenna) may be substantially similarto the first antenna 30 in function and structure such that it mayutilize a slot antenna configuration having a nonconductive slot. Secondantenna 32 may utilize a portion of housing 12 not being utilized by orpartially overlapping with first antenna 30. Similar to first antenna30, the second antenna 30 may be configured as a slot antenna includinga nonconductive slot formed by a portion of a nonconductive side wall,an air gap, or a combination thereof. The nonconductive slot may haveany three-dimensional shape such as a substantially rectangle, a square,an oval, or a circle shape formed in a portion of housing 12. The secondantenna 32 is a slot antenna having a nonconductive slot in which the“slot” is formed or bound by an upper portion, a lower portion, and twospring contacts serving as side portions of second antenna 32. The upperportion of second antenna 32, the lower portion of second antenna 32,and the side portions of second antenna 32 are all in electrical andphysical contact such that a nonconductive slot is formed inside theseportions of second antenna 32.

The upper portion of second antenna 32 is formed by a second portion ofa circumference of bezel 28 extending in an area of bezel 28 that is notbeing utilized as upper portion 30 a of first antenna 30. For instance,if the upper portion 30 a of first antenna 30 extends from first springcontact 52A (G), through second spring contact 52B (F), to third springcontact 52C (G), the second portion of a circumference of bezel 28associated with the second antenna 32 may extend between first and thirdspring contacts 52A (G), 52C (G) such that it does not include secondcontact 52B (F) (i.e., the opposite portion of bezel 28).

The lower portion of second antenna 32 is formed by a second portion ofa circumference of the printed circuit board 26 extending between thespring contacts associated with the upper portion of second antenna 32such that the lower portion of second antenna 32 corresponds to upperportion of second antenna 32. Side portions of second antenna 32 areformed by spring contacts associated the upper and lower portions ofsecond antenna 32. The nonconductive slot for the second antenna 32 maybe provided by the nonconductive side wall 42 of housing 12 betweenportions of the printed circuit board 26 and the bezel 28 between twospring contacts associated the upper and lower portions of secondantenna 32.

In the exemplary embodiment shown in FIG. 4, the second antenna 32 is inelectronic communication with the communication element 20, such thatthe second antenna 32 may wirelessly transmit and receive electronicsignals to and from any of the signal sources shown in FIG. 1, exceptfor GPS satellites (assuming that the first antenna 30 is configured toreceive GPS signals). The second antenna 32 may be formed fromelectronic signal terminals 48 and electrical ground terminals 48 on theprinted circuit board 26 and an upper portion of second antenna 32 maybe formed by a second portion of the circumference of bezel 28. As withthe first antenna 30, the length of the second portion of the bezel 28circumference may be based on a half wavelength of the signal that thesecond antenna 32 is configured to transmit and receive. The secondelectronic signal may transmit and/or receive Bluetooth™, Wi-Fi, orcellular signals, among others, and the half wavelength of the secondelectronic signal may different than the half wavelength of the firstelectronic signal, which is transmitted or received by first antenna 30.

In some embodiments, second antenna 32 may share at least a portion ofthe same signal feed (F) and electrical ground (G) connection points onbezel 28 as first antenna 30. Thus, some of the second portion of thecircumference (occupied by the second antenna 32) may overlap some ofthe first portion of the circumference (occupied by the first antenna30). In other embodiments, second antenna 32 may have entirely differentsignal feed (F) and electrical ground (G) connection points on bezel 28than the signal feed (F) and electrical ground (G) connection pointsutilized for first antenna 30. Hence, the second portion of bezel 28circumference may be separate from the first portion of bezel 28circumference such that the first and second portions do not overlap, asshown in FIG. 10e . Furthermore, the electrical connections for thesecond antenna 32 from the bezel 28 to the printed circuit board 26 maybe formed in substantially the same manner as utilized for electricalconnections for the first antenna 30.

Various embodiments of the current technology depicting differentconfigurations of the first and second antennas 30, 32 sharing the bezel28 are shown in FIGS. 10a-10g , one embodiment or configuration perfigure. FIGS. 10a-10g depict only the upper portions of first and secondantennas 30, 32. It is to be understood that lower portions of first andsecond antennas 30, 32 along a perimeter of printed circuit board 26correspond to the positions of the upper portions of first and secondantennas 30, 32 depicted in FIGS. 10a-10g . The bezel 28 is shown as anannulus with the signal feed (F) and electrical ground (G) connectionpoints on the circumference of the bezel 28 for the first and secondantennas 30, 32, which are marked and labeled. In addition, the arcuateportion labeled “first antenna” indicates the first portion of thecircumference of the bezel 28 occupied by an upper portion of the firstantenna 30, and the arcuate portion labeled “second antenna” indicatesthe second portion of the circumference of the bezel 28 occupied by anupper portion of the second antenna 32. The embodiment shown in FIG. 10aincludes only the first antenna 30 utilizing a slot antennaconfiguration and thus the only connection points for the first antenna30 are the signal feed (F) and two ground (G) connection points.

Unlike antennas that utilize an inverted-F configuration with one signalfeed (F) and one ground (G) connection points, the first antenna 30utilizing a slot antenna configuration has one signal feed (F) and twoground (G) connection points. In the embodiment shown in FIG. 10a , afirst portion of a circumference of bezel 28, extending between twoground (G) connection points, at least partially forms first antenna 30.In the embodiments shown in FIGS. 10b-10g , the first antenna 30 and thesecond antenna 32 are included, and, as mentioned above, the first andsecond portions of the bezel circumference may overlap, may abut, or maybe separate from one another.

In some embodiments, first antenna 30 and second antenna 32 maypartially overlap. As shown in FIG. 10b , a first portion of acircumference of bezel 28, extending between two ground (G) connectionpoints, at least partially forms first antenna 30 and a second portionof a circumference of bezel 28, extending between one of the two ground(G) connection points associated with first antenna 30 and a signal feed(F) connection point associated with first antenna 30, at leastpartially forms second antenna 32. As shown in FIG. 10c , a firstportion of a circumference of bezel 28, extending between two ground (G)connection points, at least partially forms first antenna 30 and asecond portion of a circumference of bezel 28, extending between a thirdground (G) connection point and a signal feed (F) connection pointassociated with first antenna 30, at least partially forms secondantenna 32. A portion of a circumference of bezel 28 is associated withfirst antenna 30 and second antenna 32 (the antenna partially overlap)in FIGS. 10b -10 c.

In some embodiments, first antenna 30 and second antenna 32 may abut oneanother and share an electrical connection point. For example, as shownin FIGS. 10d and 10f , a first portion of a circumference of bezel 28,extending between two ground (G) connection points, at least partiallyforms first antenna 30 and a second portion of a circumference of bezel28, extending between one of the two ground (G) connection pointsassociated with first antenna 30 and a third ground (G) connectionpoint, at least partially forms second antenna 32. As shown in FIG. 10d, the signal feed (F) connection point associated with first antenna 30is closer to one of the two electrical grounding points associated withthe first antenna 30, whereas the signal feed (F) connection point ofthe second antenna 32 is located an equal distance from two electricalgrounding points associated with second antenna 32. However, it is to beunderstood that the signal feed (F) connection point of the secondantenna 32 may be positioned closed to one of the electrical groundingpoints associated with the second antenna 32 such that it is configuredto transmit and/or receive signals at one-half of a frequency of asecond electrical signal.

In some embodiments, first antenna 30 and second antenna 32 may beseparate from one another. For example, as shown in FIG. 10e , a firstportion of a circumference of bezel 28, extending between a first pairof ground (G) connection points, at least partially forms first antenna30 and a second portion of a circumference of bezel 28, extendingbetween a second pair of ground (G) connection points, at leastpartially forms second antenna 32.

In some embodiments, one of first antenna 30 or second antenna 32 maywholly overlap with the other antenna. For example, as shown in FIG. 10g, a first portion of a circumference of bezel 28, extending between asignal feed (F) connection point and a first ground (G) connectionpoint, at least partially forms first antenna 30 and a second portion ofa circumference of bezel 28, extending between the signal feed (F)connection point associated with first antenna 30 and a third ground (G)connection point, at least partially forms second antenna 32.

The first and second antennas 30, 32 have been presented as eachreceiving a particular type of signal and being embodied by a particulartype of antenna. In fact, in keeping with the spirit of the currenttechnology, either antenna 30, 32 may be configured to receive any typeof signal and/or be embodied by any type of antenna. For example, thefirst antenna 30 may be configured to receive a Bluetooth™ signal. Thesecond antenna 32 may be configured to receive a GPS signal, and soforth.
